Hi,
I recently use the PDFBox librairy and I would like to change the stream
part of an object which is an AcroForm Object (a stream in PDF Form object).
in the PDF, for example we have this:
*
83 0 obj<</Subtype/Form
/Length 637
/Filter[/FlateDecode]
/Name/FRM
/Matrix[1.0 0.0 0.0 1.0 -9.21249 -82.235]
/Resources 214 0 R
/Type/XObject
/BBox[0.0 0.0599976 18.425 164.41]
/FormType 1>>
stream
some stream unreadable... that i want to change with other stream
endstream
endobj*
In the JAVA code, i am able to go to the object with the code :
// Create the PDF Document
PDDocument doc = PDDocument.load(myFile);
// Extract the catalog
PDDocumentCatalog catalog = doc.getDocumentCatalog();
// Retrieve the AcroForm
PDAcroForm acroForm = catalog.getAcroForm();
// Retrieve all fields that should be change
List listField = acroForm.getFields();
Iterator<PDField> it = listField.iterator();
// Loop on each field
while(it.hasNext())
{
// Cast to PDField
PDField field = (PDField)it.next();
// Retrive the COSObject containing the stream part
COSDictionary dicoField = (COSDictionary)field.getCOSObject();
COSDictionary mkField =
(COSDictionary)dicoField.getDictionaryObject(cosName1);
COSDictionary iField =
(COSDictionary)mkField.getDictionaryObject(cosName2);
// Here, i am on the good object (83 0) and if I print the iField, I
obtain same information as in the PDF file
// But I am not able to have acces to the STREAM part of the
COSObject/COSDictionary
}
Could you help please ? I don't know how to change the stream part. I
thought the COSOject could give me this possibility... :|
Thanks, in advance
